<div>To whom it may concern or to whom can help,</div> <div> </div> <div>I have just tried to run the Tetris game using Dr Scheme version 3.99.0.13-svn27feb2008 - but nothing happens, all the buttons except "Stop" go blank but there is no Tetris to be seeing. Ai also perviously tried with v3.72, without any luck</div> <div> </div> <div>Thank you,</div> <div>Joshua Ewulo  </div> <div>On 28/02/2008, Benjamin L.

While I was playing, though, I noticed that the lack of a mapping of the space bar to drop the falling tile was slightly inconvenient, and the lack of a scoreboard caused to game to lack some motivation for continued play.  Further, the starting speed seemed to fast, and I was constantly using the mouse to hold the game window to force the game to pause while I thought about where to place the next tile. Therefore, may I suggest the following modifications: 1) Map the space bar to a function to drop the falling tile. 2) Add a scoreboard with a stage number. 3) Add a feature to allow the user to specify both the starting speed, and the speed increments each time a row is completed (0 for no increment). 4) Add a feature to let the user map keys to in-game functions.  For example, I like to use the numeric keypad to move the tiles, and the space bar to drop the tiles.  Allow the user to specify such key mappings. Additionally, here are a few suggestions for more sophisticated modifications for the near future: 5) Add changing illustrated backgrounds (preferably Russian, since the original Tetris originated in Russia) for each stage. 6) Add background music and sound effects such that: a) The background music matches the illustrated background. b) The background music changes to a different tune matching the new illustrated background every time the illustrated background changes. c) There are different suitable sound effects for moves, rotations, drops, and completed rows. d) There are separate volume controls for both the background music and the sound effects. e) Additional background music tunes can be uploaded by the user. f) (Optional and extra credit ;-) )      The uploaded music tunes can be associated with specific illustrated backgrounds/stages by the user. 7. (Optional and super extra credit ;-) )   Add a Hextris (a hexagonal version of Tetris, popular on Sun Sparc workstations in the early 1990's) version of Tetris, incorporating all of the above.
